1. Let s be the distance traveled, in meters, and t the time elapsed during the
travel, in seconds.
Express the velocity, v, as the ratio of their intervals.
Show the units for velocity.
2. We walk up a slope.
The horizontal distance, x, traveled is 800 m.
The vertical distance traveled, y, is 60 meters.
Express the slope, m, as the ratio of these intervals and state the numerical
value of this slope as a percent.
3. Draw a graph of y = 12(x - 4)2 + 2.
At what point is the slope zero?
What is the minimum value of y?
At what point do you think the slope is -1?
At what point do you think the slope is +1?
Why?
